Valarie Austin claims she had a spotless record for four years, before she started complaining in 2012 that dentist Tuan Truong was making sexual remarks and gestures toward her and had commented to co-workers about the size of female patients’ breasts.

Austin and Truong had dated for about six months in 2011, and Truong continued to pursue Austin after she broke up with him, according to the suit.

A PSU spokesman declined comment, saying the university hadn't been served or had time to review the suit. Truong couldn’t immediately be reached for comment Monday.

Truong has been a dentist in Oregon for a decade, and has never been disciplined by the Oregon Board of Dentistry, according to its website. Austin has been a dental hygienist for six years, and also has no discipline on her state record.

After Austin complained again that Truong was trying to retaliate against her for her original complaint, Austin claims the clinic began a campaign to get her fired. She was reprimanded in writing four times from 2012 to 2014 -- for alleged instances that included using her cell phone during a patient appointment and continuing to treat the patient without changing her glove, according to the suit.

In 2013, Austin gave the Oregon Board of Dentistry the names of patients -- who were all students -- whom she suspected were pre-billed for services they didn’t receive or were double billed, her suit states.

Austin was fired on July 28, 2014, according to her suit.

The suit was filed in Multnomah County Circuit Court by Portland attorneys Kyann Kalin and Peter Stutheit.
